This 'invention relates to v"improvements in ,drip` valves for sterilizers, particularly adapted for use in machines for the. vPas y madea teurizationiot milk. l v

An object ,'Yofthis invention is to provide amain Ivalve, in such a manner that lwhen closing the main valve the drip valve will open, and When opening the mainval've the drip valve will functionto close. A l

A furtherV object of kthis invention'isto provide Ta milk detector or drip which `Will function to work in conjunction with thel inainfvalve'; in a Pasteurizver, vWlhze'rein@the main valve functions-to closeof the nsupplyr 'of milk vfrom the a'steurizyer; but in orditorrmanyreasons.. vvThe dripv valve, accord-y nary practice, a slight leakageu occurs during V the vperiod of Pasteurization andthisleakage or ldrip' ordinarily `flows.. into the Pasteurized` product, AWhich isobje'ctionable hing'fto Vthis invention, provides an `eliicient meansfor eliminating the leakage problem;y yAnother objectofthis inventionis to providea .valve device especially adapted .for use. on apparatuse-mployed in the `milk industry, including Pasteurizers, although it may be'used also for a number of other purposes wherefvalves or drips arev common.

This invention provides a combination of amain valve having a lstem and 'means con-f nectedy with the stem for opening and closing the mam valve, a dripV valve, and antol matic means fory opening` the fdrip valve when closingthemain valve andl closingthe drip valve When opening the 4'mam valve,

consisting of a suitable connecting element between the stem and the drip valve. Arturther object of this invention is to provide means for sterilizing the valve mechanism by means of a. steamlinef-suitably connectedv to the valve -mechanisml'in such a manner that when the drip valveis `openjthe:steam Will circulate through the valve "mechanism at the Vsame time the drip or leakage Will be allowed to flow into a suitable sanitary pipe line, the line being properly closed by means of sanitary' fittin0's.

f `nother object of this invent-ion is to provide a valve mechanism Which may be connected to the Pasteurizer Without necessita-tn *ing objectionable crevices or curves `formed in tlielining of the Pasteurizer. j Other objects of this invention will appear ,from the foiiiewirigjlaaii'ed -`me coMrANY, orvRUTLfiism, VERMONT.
